With the development of the Web, an information “Big Bang” has taken place on the Internet. The continued rapid growth in information volume makes it increasingly difficult to find, organize, access and maintain the information required by users. Today, when we use a web search engine, the search engine can’t tell if the web page is actually relevant for our search. This research paper critical...

the hcci combustion process is initiated due to auto-ignition of fuel/air mixture which is dominated by chemical kinetics and therefore fuel composition has a significant effect on engine operation and a detailed reaction mechanism is essential to analysis hcci combustion. a single zone-model permits to have a detailed chemical kinetics modeling for practical fuels. in this study a single-zone ...

In this study it has been tried, to compare results and convergence rate of sensitivity analysis and conjugate gradient algorithms to reduce fuel consumption and increasing engine performance by optimizing the timing of opening and closing valves in XU7/L3 engine. In this study, considering the strength and accuracy of simulation GT-POWER software in researches on the internal combustion engine...

ethanol as a renewable and alternative fuel when utilized in homogeneous charge compression ignition (hcci) has potential to substantially reduce nitrogen oxides (nox) and particle matter (pm) and can maintain hcci sustainability. hcci engine operation is limited between two ringing and misfire regions that too retard and advance combustion phasing highly affect hcci engine operation, performan...
